The team at Texas Children's Fetal Center, a national leader for treating fetal anomalies, has successfully completed two in-utero fetal cardiac interventions to treat hypoplastic left heart syndrome (HLHS), a congenital heart defect that is one of the most complex heart defects to treat. The first center in the Southwest to create a program to treat this defect in-utero, Texas Children's Fetal Center and Heart Centers are proud to be able to offer this procedure to future HLHS patients looking for hope for their unborn babies.

"Previously, patients had limited options for their babies when they received an early diagnosis of HLHS during a routine ultrasound," says Dr. Michael Belfort, obstetrician and gynecologist-in-chief at Texas Children's Hospital and chairman of the Department of Obstetrics and Gynecology at Baylor College of Medicine. "From this moment on, through the collaborative work of the Fetal and Heart Centers at Texas Children's Pavilion for Women, we can offer more options to families who otherwise would have little hope."
HLHS is a condition that occurs in approximately 1 in 6,000 live births when the fetus's left side of the heart does not develop normally. Because most of the structures on the left side of the heart are too small and underdeveloped (hypoplastic), it is difficult for the heart to provide enough red blood flow for the body's needs. All children with HLHS will undergo at least three surgeries within the first three years of life. However, if diagnosed early using a fetal ultrasound, some fetuses may be a candidate for the new in-utero catheterization procedure that will help treat HLHS and allow them to be more stable at birth before having to undergo their first heart surgery.
"Thanks to our collaboration with the Fetal Center, our heart program is now so comprehensive that we are in the position to offer care not only to fetuses in-utero but are able to take care of these patients all the way into adulthood. Our expertise ranges across all ages of patients with congenital heart disease," said Daniel J. Penny, chief of cardiology at Texas Children's Hospital and leader of pediatric cardiology at Baylor College of Medicine (BCM).
Texas Children's Fetal Center experts have cared for four fetal intervention patients in the last four months. Each case has varied slightly. The first two Texas Children's patients were taken to Children's Hospital Boston where they were treated in collaboration with the Texas Children's team for critical aortic stenosis or a severely obstructed aortic valve. These types of critical aortic stenosis are typically detected mid gestation and, develop into HLHS at the end of the pregnancy. The left side of the heart stops growing and becomes severely underdeveloped, rendering it inadequate to support the systemic cardiac output.
The third and fourth patients were treated at Texas Children's Hospital. For the most recent two patients, physicians were dealing with a rare type of HLHS where the fetus had an intact atrial septum (IAS), a severe congenital cardiac malformation with little possibility of postnatal survival, even with a cardiac intervention performed immediately after birth.
